How do you do a bridge in an essay?

The key to constructing good bridges is briefly repeating what you just finished saying, thus forcing yourself to spell out how the new paragraph follows. Hence, “Next,” “Additionally,” and “My next point is” are not explicit transitions.

What materials do you need to make a bridge?

Some of the main materials found on a bridge are steel, concrete, stone and asphalt. Other materials include iron, timber, aluminum, rubber and other joint materials. Below is a description of some typical uses for these materials in a bridge.

What steel is used for bridges?

Weathering steel or, to use its technical title of 'structural steel with improved atmospheric corrosion resistance', is a high-strength, low-alloy structural steel that, in suitable environments, may be left uncoated because it forms an adherent protective rust 'patina' that minimises further corrosion.

Is copper used to make bridges?

One of the materials that can help build better bridges is called shape memory alloys (SMAs). They are a combination of nickel and titanium – though sometimes copper, zinc, aluminum, iron, manganese and silicon are used as well – that can be deformed and then returned to their original shape.

Which metal is used in construction?

Metal alloys used in building include bronze (mainly copper and tin); brass (copper and zinc); monel metal and nickel silver, mainly consisting of nickel and copper; and stainless steel, with important components of nickel and chromium.

What is RCC made of?

Its full name is reinforced cement concrete, or RCC. RCC is concrete that contains steel bars, called reinforcement bars, or rebars. This combination works very well, as concrete is very strong in compression, easy to produce at site, and inexpensive, and steel is very very strong in tension.

Is it OK to use rusty rebar in concrete?

slightly rusted rebar has better bond to concrete than uncorroded rebar. If the concrete is 'good' further corrosion will be minor as the concrete should be sufficiently alkaline to prevent rusting, and dense enough not to permit enough 'water or air to reach rebar to cause corrosion.

Can I use rusty rebar in concrete?

As long as there is not loose, flaky rust, the concrete will bond to it better than a smooth, or painted surface. Re: Rusty Rebar?!? Do NOT weld rebar and then put the welded joint in the concrete, that is not allowed by building codes. Virtually all rebar has that thin film of rust on it.
